is it possible the torque converter got overheated and burnt ? I,m not sure where to test clutch pacs ? I'm not seeing them in the parts book breakdown, hope everything works out ok with your wife
Mechanic: Curtis B., Technician replied 4 years ago

Torque convertor can be worn to the point, it will not pull, but not the usual problem. Has transmission oil been drained and the oil checked for any metal that would indicate a large amount of aluminum from convertor ?

I will have my guys check that in the morning , its been jut sitting in the yard since late last winter , like I said start it up you wouldn't think anything wrong run it 10 mins and stops moving
Mechanic: Curtis B., Technician replied 4 years ago

You say the transmission pump, driven by the torque converter was replaced? Still sounds like pressure is dropping.

y guys called it a charge pump it was outside someplace they did not take anything part transmission wise
Mechanic: Curtis B., Technician replied 4 years ago

Looking back at the 590-SL, 1996 year, it has no charge pump, just the main transmission pump, driven by the torque converter.

I don't know what they changed I didn't see one either but I didn't want to sound too dumb , so I guess my choices are change the filters ,probably cut them open to see if any metal I guess it becomes pretty major , pull transmission , change torque converter , I suppose the metal could come from the clutches ? ug ! also ?
Mechanic: Curtis B., Technician replied 4 years ago

First check the strainer!
